“I didn’t go to religion to make me happy. I always knew a bottle of Port would do that. If you want a religion to make you feel really comfortable, I certainly don’t recommend Christianity.” (C.S. Lewis: ‘God in the Dock: Essays on Theology and Ethics‘)
He went on to say that he hadn’t become a Christian because he thought it would make him happy – rather, he had come to Christian faith because he had decided it was true. In case you’re interested, he tells the story of how he came to that conclusion in his autobiography ‘Surprised by Joy‘.
I think this is exactly right. Yes, Jesus promised us joy, but he’s not in the business of confirming us in our selfishness and self-centredness. His business is to transform us into people who can truly be happy forever, and in order to do that, he has to help us leave behind a lot of things we think are essential to our happiness. This is because he knows a lot better than we do what is good for us and what isn’t. So the best thing to ask, as he says in the introduction to ‘Mere Christianity‘, is ‘Are these doctrines true? Is holiness here?’ Put happiness first and we probably won’t find it. Put truth, loving action, and holiness first, and we’re likely to get happiness thrown in as a by-product when we’re least expecting it.
